Answer 2

Answer:

13/12

Step-by-step explanation:

We know that if an integer has a negative power then, the nos. of the integer are reversed to get the positive no. of power.

Therefore,

$2^{-1} + 3^{-1} + 4^{-1} \\= (\frac{1}{2}) + (\frac{1}{3}) + (\frac{1}{4})$                 [by taking the L.C.M. of 2,3,&4=24]

$\frac{12+8+6}{24} = \frac{26}{24}$

on simplifying 26/24 we get, 13/12
